Re: Kafka stats description
Hi Jun

As per my understanding:

TotalFetchRequestMs - Total time of fetch requests in *microseconds*

AvgFetchRequestMs - Average time of all fetch requests in *microseconds*

MaxFetchRequestMs - Maximum time of a fetch request in *microseconds*

**
Here I am taking Ms as Microsecond.

Am i right or missing something ?
